Review on High Speed Class 10 Micro SD Card 512GB Memory Card 📸 with SD Card Adapter - Designed for Nintendo-Switch, Android Smartphones, Tablets, and More by Ronnie Polk

At first glance, that seems like a lot. Put it in my Samsung tablet and it will recognize it as the right size. But whenever I copied files to it, 80%-90% of those files were unreadable. I've used a program that also checks the data integrity on the card and it always returned 75% to 90% corrupt data. After several attempts I gave up and sent it back. Be careful when purchasing this card.
